Establishing an accurate load is critical to testing and evaluating a PC power supply. PCPerspective’s power supply test bench can place a precise 2,000 watt DC load on the PSU under test. Each power supply is tested under controlled, real-world conditions up to its maximum rated load (at 40ºC), using both 115 VAC and 240 VAC line voltage. Our current suite of tests includes:

• DC Load Regulation

• DC Line Regulation

• DC Cross-load (unbalanced load)

• AC Ripple and Noise

• Power Factor

• Efficiency

• Differential Temperature

• Noise

The Ultra X3 600W modular power supply was evaluated on both features and performance. A full range of equipment was used to test the power supply under controlled load conditions.
